How To Choose A Perfect Saw Blade

Before buying the new blade, you need to focus on a few things to get the perfect blade for your saw. Let’s have a look at those things. 

  1. The diameter of the blade: You will find the diameter of the blade at the sticker attached to the blade. Sometimes it is also written as the size of the blade.

If you don’t find the diameter of the blade, just remove the blade and measure from one side to another side by using a measurement tape. 

  1. The arbor diameter of the saw: Before buying the new blade, always take the measurement of the circular saw arbor. The arbor helps to fit the blade properly with the saw. 

The diameter of the arbor is always printed on the sticker of the blade or in the saw. If you don’t find it, just measure the arbor diameter after removing the blade. 

  1. The RPM: If you are a regular saw user, you are surely familiar with the RPM. RPM means revolutions per minute. 

Each saw and blade has an RPM rate and before buying the blade, make sure that the new blade RPM rate doesn’t exceed the saw RPM rate. 


  • Don’t forget to wear hand gloves when doing any repair with the blade. 
  • Engage the blade lock properly to avoid any kind of unwanted injury.
